Personally I interpret the news is that they have discovered a generic
precomputation attack against all ciphers. It seems odd that Secret and
Unclassified should now be encrypted at 256-bit.

Or, do we copy the triple DES construction and do EC-RSA-EC?  Chosen

Not really faster. To encrypt the RSA key, you'll have to do about 6 ECC
encryptions in parallel. So it'd become as slow as RSA.
